Autonomous Mode

A harmonic effect on a modified Anishchenko-Astakhov generator capable of demonstrating two-frequency quasi-periodic oscillations in the autonomous mode is considered. The possibility of doubling the three-frequency tori in a non-autonomous system is shown. The possibility of the effect of chaos suppression by an external signal is demonstrated, which leads not only to periodic, but also to quasi-periodic modes when the influence amplitude exceeds a certain threshold.

This paper considers the dynamics of a three-dimensional nonlinear autonomous system that models the behaviour of an electrical circuit. Results on the existence of stable periodic oscillations and the behaviour of Poincaré–Bendixon types are obtained. The work is based on a variation of classical monotone systems theory.

Typical Time

Three distinct kinds of rapid variations have been detected in the light curves of dwarf novae: rapid flickering, short period coherent oscillations, and quasi-periodic oscillations. The rapid flickering is seen in the light curves of most, if not all, dwarf novae, and is especially apparent during minimum light between eruptions. The flickering has a typical time scale of a few minutes or less and a typical amplitude of about .1 mag. The flickering is completely random and unpredictable; the power spectrum of flickering shows only a slow decrease from low to high frequencies. The observations of U Gem by Warner and Nather (1971) showed conclusively that most of the flickering is produced by variations in the luminosity of the bright spot near the outer edge of the accretion disk around the white dwarf in these close binary systems.

Operating Temperature Range

The vast majority of electronic devices on-Board Russian spacecraft is placed on a temperature-controlled mounting surface is ON, however, in some tasks there is a necessity to place a separate electronic units out thermostated panels on remote spacecraft design. The article presents an autonomous system of providing thermal regime of electronic blocks of spacecraft and objects of space technology that require maintaining the operating temperature and are unable to be installed on the thermostatic landing surfaces of spacecraft. The proposed autonomous system of providing thermal regime can operate autonomously in the extended operating temperature range of the installation surface from -80 to +80 °C when the supply voltage changes in the range from 75 to 550% of the nominal value. The review of the existing solutions is presented, the substantiation of the proposed decision is given, the structural scheme of autonomous system of providing thermal regime is given and its description and an example of application is given.
